Question

in a lottery game, there are 2 winners for every 100 tickets sold. If a man buys 10 tickets, what are the chances that he is a winner

Answer 1

Answer:

The chances of the man being the winner is 20%.

Step-by-step explanation:

Given:- 2 winners for every 100 tickets.

To Find:- Probability of a man being a winner if he buys 10 tickets.

Solution:-

There are 2 winners for every 100 tickets sold.

So, there will be 1 winner for every 50 tickets sold.

The probability of a man being a winner if he buys 10 tickets will be

$\frac{10*1}{50}$ = $\frac{1}{5}$

Therefore, the chances that the man is the winner is 100 × $\frac{1}{5}$ = 20%.

Answer 2

Answer:

The chances that he is a winner is 20%

Step-by-step explanation:

As per the data given in the question,

We have,

No of winners in each game = 2

Total no of tickets sold = 100

Hence, winning probability = $\frac{2}{100} =\frac{1}{50}$

Now,

No. of tickets he bought = 10

So, his winning probabilty = $10\times\frac{1}{50}= \frac{1}{5}$

Hence, chances of wining is $\frac{1}{5} \times 100 = 20\%$

Therefore, the chances that he is a winner is 20%
